Caché

Hello,

Here's the code:

Hi,

I'm posting this for the benefit of others. Not often one changes certificates in Cache, at least in my case. I run a system, that uses certificates to encrypt SOAP messages, and since the last time I ran it, my certificates expired.

So I renewed them using our PKI tool, so far so good. I gave all (3) certificates the same names (and filenames too) as to those expired, thinking that everything would just work fine next time I call the SOAP service.

Unfortunately, I got trapped.

I've been using iFind indices in one of my applications but this morning discovered that the index is missing data. I confirmed the issue also exists in our test environment and rebuilt the indices there. That seems to have fixed the immediate problem. However I'd like to understand how this came about to avoid it happening in the future.

Has anyone encountered this before and know the cause?

When refreshing a html or tablePane component using refreshContents() that takes a lot of server-side-processing, I'm running into timeouts every now and then. i.e., the result for the tablePane is that there's nothing displayed at all.

How can we configure (relax) that timeout so also those heavier ones get refreshed eventually? Just overriding %request.Timeout in %OnPreHTTP did not seem to do the trick.

I have a Cache classes with %TimeStamp (e.g. 2016-04-18 12:29:11) and %Date (eg. 64027) properties. And I have a javascript client app, which needs full CRUD over this properties.

But in javascript date/time are defined by ISO8601 (e.g. timestamp 2016-04-18T12:29:11Z, date 2016-04-18).

Does Caché support SQL CREATE SEQUENCE as in PostgreSQL?

If not, what would be the best alternative? Create my own sequence logic as the example bellow? 

MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.

Any chance of adding support for MessagePack?

Hello,

I hereby announce the creation of an IRC channel dedicated to Caché development:

* network: FreeNode (connect to server: irc.freenode.net)

* channel: ##cos (yes, two hashes).

Topic is anything related to Caché development in spite of the name (and the fact that of Caché development I only really know about COS anyway), so sorry in advance for the restrictive channel name :)

Waiting for you here! (my nick is idletask on freenode)

During a fine breakfast at Global Summit 2016 I was asked about the %DEFAULTDB database that now appears when creating the %ALL namespace.

I interested on how others feel on this subject.  In general terms when you have a class that extends from %XML.Adaptor and you call XMLExport no validation is automatically done as part of the XMLExport process.  As an example if you do the following

Hello!

Link: https://demo.cachequality.com

In this presentation, developer oriented, we will cover this tool, how it works, how you can use it/administer it, etc. Duration 30 minutes.

The topics will include:

• a short presentation of Caché Quality and SonarQube (which this plugin uses),
• a demonstration of the rules and how to tailor them to your need.

Questions will be more than welcome! Hope to see you there!

And a big thanks to Evgeny Shvarov who made this possible!

Here's my code (download):

Class Utils.Generators [ Abstract ]
{

ClassMethod B()
{
    s ^a = 1
}

ClassMethod A() [ CodeMode = objectgenerator, GenerateAfter = B, PlaceAfter = B ]
{
    k ^a
    do ..B()
}

Now, obviously for it to work I need method B compiled and ready to use before compiling method A().

I test it with the following code:

Presenter: Saurav Gupta
Task: Provide customized authentication support for biometrics, smart cards, etc.
Approach: Provide code samples and concept examples to illustrate various custom authentication mechanisms
 

Description: In this session we will discuss customized way to solve various authentication mechanism and show case some sample code.

Problem: Using custom Authentication mechanism to support devices like biometrics, smart cards, or create an authentication front end for existing applications.

Solution: Code samples and concept examples.

Presenter: Anton Umnikov
Task: Run SQL queries quickly on huge amounts of data
Approach: Use a shared-nothing architecture to leverage a cluster of small, cost-effective servers
 

Explains how a shared nothing architecture allows you to leverage a cluster of small, costeffective servers to serve query results that would have taken much longer on a single, big and expensive box. This brings affordable horizontal scalability.
